Supersonic flight over the continental U.S. is prohibited because of the potential damage from sonic booms, i.e., pressure waves from the jet that slam into the ground.
Kromberg & Schubert, an automotive supplier in Germany, has developed the first 3D molded-interconnected-devices (3D-MID) made from a new laser-structurable polyamide: Electronic conductors are integrated directly into the 3D-MID surface.
Laser light rather than heat can strip hydrogen atoms from silicon surfaces, sayresearchers at the University of Minnesota, Vanderbilt, the University ofTennessee, and Oak Ridge National Laboratory.
A five-axis laser-machining process forms complex geometries into gas-turbine blades and vanes with a level of accuracy previously possible only with EDM.
